Note:
Power consumption (Pd), junction-to-case thermal resistance (θj-c), heat sink thermal resistance (θf(wàn)), junction
temperature (Tj), case temperature (Tc) and ambient temperature (Ta) have the relationship shown in the
following equation.
Tj=Pd(
θj-c + θf(wàn)) + Ta
=Pd×
θj-c + Tc,
*Tc=Pd×
θf(wàn) + Ta However, Tj max is limited by Tstg max (150°C)
